TO ALL WHOM IT MAY CONCERN:

,Be itknown that I, PETER H. NILES, of'Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and useful Improvement in Portable Lunch-Boxes; and I do hereby declare that the following is a full and exact description thereof, reference being had'to the annexed drawings, and to the letters-of referonce marked thereon.

To enable others skilled in the a'rt'tomake and use my invention, I will proceed-to describe its constrnc. tion and operation. Upon the accompanying drawings- Figure 1 is .an elevation of the box, expanded.

Figure 2 is an elevation of the box collapsed.

Figure 3 isan elevation of the box in the act of collapsing.

Figure4, a plan of the same, showing the sides folded back.

The top, a, and bottom, 6, of the box are connected to the end-pieces c byhinges, and are cut sufliciently long to admit of a ledge, 12, being turned down at both ends on the outside to support the end-pieces c. A springmovement is given to the top, by making it slightly concave to secure the sides firmly when the box is formed, The end-pieces c are double-acting, being in two horizontal sections, and so hinged to the, top and bottom, and

to themselves, that they collapse inwardly. Thesides e are hinged to the bottom, and either fold back against its outside when the box is collapsed, or occupy the space between the top, bottom, and ends when it is formed, and are prevented from passing in too far by the wired stopf, formed on the insideqf the top- The ringsg are for the purpose of opening the sides.

The box being for-med, to collapse it, pull out the sides by the rings and fold them' back against the bottom. Press the end-pieces inward, and the top and bottom shut together. To form the bbxfpull the top and bottom apart, straighten the end-pieces, and bring up the sides, pressing them squarely under the edge of the top.

-I.c1aim a. portable collapsing lunch-box, composed of a top and bottom, in combination withfdouble-acting end-pieces and single-acting sides, substantially as described.'
